		//1.实现写死的json字符串,解析展现到页面上
		var jsonstr = '[{"p":"17888.00","op":"17888.00","cbf":"0","id":"J_100013651682","m":"27999.00"}]';
		//2.获取价格和编号
		var obj = JSON.parse(jsonstr); //把字符串转换成js对象
		var price = obj[0].p; //获取到数组第一条记录,访问p属性
		var id=obj[0].id;
		
		console.log(price);
		console.log(id);
		
		//3.将内容写道页面,进行展示
		$("#id").text(id); //span属性标签写法
		$("#id").css("color","blue"); //渲染
		$("#price").text(price).css("color","red");
